MODCHQ - SET UP AND MAINTENANCE Ó UNCTAD – SITE (V1.15) 10.5 Customs Headquarters Functions The  functions  for  set-up  and  on-going  maintenance  of  the  ASYCUDA++  system  are  contained within Module  MODCHQ.  This  Module  is  also  called  the  Customs  Headquarters  Module.  Within this module 'Headquarters' staff set up the System control tables that contain all the reference data necessary  to  run  ASYCUDA++.  In  a  'live'  ASYCUDA++  installation,    MODCHQ  is  used  for  the routine maintenance of control table data and for statistical report extraction. Control  tables  include  the  Customs  Tariff  and  all  components  of  the  Tariff,  Tax  and  Duty  rates, including preference, Customs Procedure Codes and Currency Rates of Exchange. Other control tables, grouped within the headings  ‘Operational  Environment’  and   ‘Transaction Controls’ , cover Customs Office and Warehouse codes, Declarant and Company codes, Carriers, Banks, Budget and Tax Codes, Countries, Currencies and Modes of Transport. MODCHQ also contains a number of pre-defined reporting formats for extraction of national trade statistics  and  loss  of  revenue  statistics  from  the  transaction  database.  The  reporting  options  are sufficiently flexible to meet most general reporting needs. For  an  understanding  of  the  process  of  setting  up  a  national  tariff  structure  or  regime,  applying taxation  rates,  and  the  use  of  ASYCUDA++  'Rules’,  see  Section  9  of  this  Reference  Document ‘National Configuration’. The Functional Menu of MODCHQ Options on the main menu for Module MODCHQ ('Functions') are as below: Connecting to the Server Section 2, ‘Using ASYCUDA’, explains the server Login procedure. Note: Most of the menu options in  MODCHQ require that you be logged on to the server. This is because any alterations to control tables are made directly to the System files on the server.
